1. Molecule A has a partition coefficient of 4 and a molecule B has partition coefficient of 2. Which molecule, will move faster across the membrane and why?
2. What is the osmolarity of 2M Fe2(SO4)3solution (write the units too)?
Homework Answers
Answer
1. Molecule A with partition coefficient 4 will move faster across the membrane. The higher the partition coefficient, higher will be solubility and one with greater solubility will pass more quickly across the membrane.
2. Fe2(SO4)3 solution will dissociate into, Fe2(SO4)3 ------------>. 3Fe+ +SO4- (4 ions)
. Osmolarity = Molarity X dissociated ions
. = 2 mol/L X 4 ions
. = 6 Osmol/L

B. Molecular size: What is the initial osmotic gradient when the RBC’s are placed in 300 mM methanol? What molecules contribute to the osmolarity of the cytoplasm? of the surrounding solution? Does the osmotic gradient change over time as the RBC’s remain in the 300 mM methanol solution? In this scenario, which molecules are moving across the membrane, the methanol or the molecules inside the cell? What causes these molecules to move? How do they cross the membrane? What affects...
